Support of high pathloss mode

Abstract

Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a user equipment and / or base station) may operate in a first mode in a wireless network over a radio frequency spectrum band. The wireless device may receive a signal indicating that a value of the radio frequency spectrum band has satisfied a threshold value. The wireless device may switch, based at least in part on the signal indicating that the value has satisfied the threshold value, from the first mode to a second mode for wireless communications in the wireless network, wherein a first length of a first synchronization signal block associated with the first mode is shorter than a second length of a second synchronization signal block associated with the second mode.

Description

CROSS REFERENCE[0001]The present application for patent claims the benefit of U.S. Provisional Patent Application No. 62 / 814,564 by LI et al., entitled “SUPPORT OF HIGH PATHLOSS MODE,” filed Mar. 6, 2019, assigned to the assignee hereof, and expressly incorporated herein.INTRODUCTION[0002]The following relates to wireless communications, and more specifically to managing a link budget in a pathloss environment.[0003]Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) s...

AI Technical Summary

Benefits of technology

The patent describes a method, apparatus, and computer-readable medium for wireless communications in a network. The method involves switching between different modes based on the value of a threshold value to adapt to the channel conditions and support wireless communications. The apparatus includes a processor and memory to operate in a first mode and switch to a second mode based on the threshold value. The technical effect of this patent is to provide a more flexible and adaptable method for wireless communications in a network, even in scenarios where the pathloss between devices exceeds the ability of some techniques to accommodate larger variations in pathloss.

Problems solved by technology

Due to a variety of conditions, the channel (or path) between the communicating devices may experience interference, blockage, etc., such that the wireless communications may fail.

However, such techniques are only suitable when the pathloss (e.g., the interference, blockage, etc.) between the communicating devices is within a given range.

However, some deployment scenarios may experience excessive pathloss, e.g., such as in a millimeter wave (mmW) network, that exceeds the ability of some techniques to accommodate larger variations in pathloss.

For example, some techniques may not support wireless communications when the pathloss value / transmission power level between the communicating devices satisfies or otherwise exceeds a threshold value.

In these instances, wireless networks may be unable to support wireless communications.
